1) Go to some page (I use about:home)
2) Open a site that takes a few seconds to load. An easy one is (warning: will hang Firefox for 5 seconds).
3) While it's loading, push the back button.
4) Look at the page in the AwesomeScreen.

Expected result:
Page will either have no title or the correct title.

Actual result:
Page's title changed to the previous page - in this case, "Fennec Start".

I was able to reproduce this on a number of sites (Google search, Zimbra, and the link given above).
Attached patch patch (obsolete) — Splinter Review
Following this sequence of events:
* Load about:home
* Load slow page
* Click back during load

we can apparently get a DOMContentLoaded event for the slow page *after* we receive a document start event for about:home. This patch makes sure we match titles with their correct page URLs in these cases.

IRL we talked about not changing updateTitle and just testing in the handleTitleChanged and handleContentLoaded.

It doesn't feel right to add pass the url to updateTitle for checking internally.

Attached patch patch v2Splinter Review
If we set the URL on location change, we don't have to worry about setting the tab URL too early (which means we don't need to worry about events being out of sync with the tab state).
